Embryo research and public policy: a philosopher's appraisal.

The development of public policy on bioethical issues can be approached through substantive moral and philosophic reasoning, or through balancing perceived societal views as to what is ethically acceptable. The Human Embryo Research Panel had to apply the first approach to the question of the moral status of the preimplantation embryo. Only after concluding that the preimplantation embryo was not a full human subject could the panel consider the conditions under which embryo research was ethically acceptable, given a range of societal views, concerns, and interests.
